To be sure, someone's listening out there. Far more scanners tuned to HAM repeaters than HAM rigs. Hmmm, well mebbe not so many more these days as scanning has become even more of a niche or fetish than HAM.

I hear ya. Oft have I cried out during a heated jt65 exchange "move the fan, for I've got the vapours!" and no one was near to comply! Woe is me.

Yeah not like there's 34 pages of frequencies and links to freqs right here or anything.

How location specific are the frequencies? It's not like it's HF where you have a chance of hearing it no matter your QTH  :)


On this page, that I've linked to in several places in this very thread, is a box where you can enter your zip and see logs from within whatever rx range chosen;

Keep in mind that I routinely hear HUNTRESS and several other east coast commands here in sw Indiana, via an ancient scanner attached to a HAM triband vertical mobile antenna hanging in the window on the ground floor. When they're 50k ft up you can hear them a long ways.

i havenít heard anything rither Josh, so Iíll be interested to know what you find.

Lol I was hoping you'd catch this post before 2200 and tune in!

Nada heard that day, a look out the window shows plenty of daylight left so really shouldn't expect to hear this, especially with a horizontal, a vertical might stand a chance. 10 minutes till showtime!

Have to wonder how many of their target audience has bfo capability.

Yeah this thing is way cool and great price.
Was thinking the other day with this thing having that fat display and processing ability it's not too far fetched for someone to roll out a similar in size and price fft/waterfall display with say 70MHz, 45MHz, 10.7mHz, 9MHz, and 455kHz inputs as a stand alone panadaptor that can be bodged into just about any rx. I'd love to have one.

Like this thing but rationally priced;

If you privateer the am and/or fm airwaves, let this be your warning.

I got one, the most amazing thing is it actually works to the degree expected. No dsp seen so far, just analog chips and discretes.

On  like note, the HAM repeater traffic I hear is always the same few people who know each other locally, not newcomers or even people driving past the area - however that does happen. I suppose this is to be expected among friends. So, if people don't have anything to say or anyone they actually want to talk to, we might rationally expect more digital modes where pc talks to pc in the future. I like them in the sense I get to see how far away my peanut whistle can be heard, but they're hardly a qso mode.

There is/was a crew who ran 300 baud packet, kb to kb, on 20m who welcomed newcomers. Well, at least there was, dunno if they still play there or not. Packet on hf is neat because it's not supposed to work there but it does. Also on a like (BFSK) note, there are guys who will ragchew on rtty, just gatta catch them.

I hear mil-air stuff.  I am sure there is a lot of traffic Chris can hear.

The 225-400 band is big and it is easy to miss stuff.  Maybe start with some power surveys to identify good target frequencies?  Try this:

http://kmkeen.com/rtl-power/

The saving grace of the rtl is it has a autotuning v/uhf bandpass filter that comes into play on those bands. It can be narrowed to 30 or mebbe it was 300kc. Not all apps for the rtl mention this filter but it's built in the hardware, dunno if the hardware does it automagically or if the app must expose the functionality and the user select it.

HDSDR is my fav app for rtl by the way, your cpu won't even notice the app is running.
